As boys change from Cub Scouting to Boy Scouting, the transitioning adult leaders must understand the different nature of their roles as Boy Scout leaders. In Cub Scouts they were in control of their den and led the boys in a program tailored by them. The adult Cub leaders study the book, set goals for their dens, and push/encourage their Cubs and Webelos to achieve as much as they can, as quickly as they can. It is a wonderful program, one most of us adults and most of our boys have experienced.
Boy Scouts, on the other hand, is designed to teach young men to be leaders. The Troop is led by the Senior Patrol Leader and by the Troup Leaders Council (TLC-see description in T-351 guidebook). The Scoutmaster (SM) or his designated Assistant Scoutmaster (ASM) is there to guide the TLC as it runs the Troop. With a troop as large as ours, the Scoutmaster needs the support of many Assistant Scoutmasters. He may assign them to certain areas or simply rely on them to be there to assist at meetings.
